Abstract (en)
[origin: CA2873729A1] A smoke detection unit has two identical smoke detectors juxtaposed horizontally, each made up of at least one smoke sensor positioned beneath and coupled to a measuring chamber fitted with walls. The detectors are encapsulated in a rigid cavity having an upper base and a lower cover positioned opposite the smoke sensors. A base is formed by the walls of each of the two measuring chambers. A method further fixes the smoke detection unit to a bearing structure.
